Trevali Discoveries Multiple New Zones of High-Grade Mineralization
at Santander Zinc-Lead-Silver Mine
Highlights include: Pariatambo Zone - 9.35 metres of 4.0 oz/ton
Ag, 6.5%Pb, 8.9% Zn
Rosa Zone - 8.75 metres of 5.6 oz/ton Ag, 3.6% Pb, 5.1% Zn, and
4.3 metres of 5.1 oz/ton Ag, 4.2% Pb, 5.6% Zn
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct 8, 2013) -
Trevali Mining Corporation ("Trevali" or the
"Company")
(TSX:TV)(TSX:TV.WT)(LMA:TV)(OTCQX:TREVF)(FRANKFURT:4TI)
announces that underground drilling at the Santander
Zinc-Lead-Silver Mine in Peru has intersected multiple zones of
high-grade polymetallic mineralization that remain open for
expansion.
The 3,968-metre drill program, in 39 holes, was designed to
explore and define new footwall mineralized zones encountered in
recent underground development in addition to provide deeper
in-fill definition information on the Magistral Norte deposit to
facilitate long range mine-planning.
Three new zones occur in the footwall (or behind) the principal
Magistral Norte deposit. The Pariatambo and Manto Zones lie
parallel to and in the footwall of the main Magistral Norte Zone
(Figure 1). However, the new Rosa Zone, also in the footwall, is
oblique (approximately 80?) to the main mineralized structures and
is thought to represent the later phases of replacement
mineralization along a paleo fault, which is part of a set of
faults conjugate to the main north-south structures (Figure 2).
Due to the orientation, the Rosa Zone has been under-explored.
The majority of previous surface exploration drill holes were aimed
parallel to the Rosa Zone, leaving it for the most part undetected.
All three zones remain open for expansion. Intercepts are shown in
Table 1 and locations shown in Figures 1 and 2.
"These drill results give Trevali added confidence in mine
planning and scheduling going forward with the added bonus of new
mineralized material in the footwall, which is easily and
immediately accessible for mining from the Magistral North ramp,"
stated Dr. Mark Cruise, Trevali's President and CEO. "Based on the
results to date we classify the Rosa zone upside as significant and
aim to expand upon these results in the near future."

This news release contains "forward-looking statements" within
the meaning of the United States private securities litigation
reform act of 1995 and "forward-looking information" within the
meaning of applicable Canadian securities legislation. Statements
containing forward-looking information express, as at the date of
this news release, the Company's plans, estimates, forecasts,
projections, expectations, or beliefs as to future events or
results and the company does not intend, and does not assume any
obligation to, update such statements containing the
forward-looking information. Such forward-looking statements and
information include, but are not limited to statements as to: the
accuracy of estimated mineral reserves and resources, anticipated
results of future exploration, and forecast future metal prices,
anticipated results of future electrical sales and expectations
that environmental, permitting, legal, title, taxation,
socio-economic, political, marketing or other issues will not
materially affect estimates of mineral reserves. These statements
reflect the Company's current views with respect to future events
and are necessarily based upon a number of assumptions and
estimates that, while considered reasonable by the Company, are
inherently subject to significant business, economic, competitive,
political and social uncertainties and contingencies.
These statements reflect the Company's current views with
respect to future events and are necessarily based upon a number of
assumptions and estimates that, while considered reasonable by the
company, are inherently subject to significant business, economic,
competitive, political and social uncertainties and contingencies.
Many factors, both known and unknown, could cause actual results,
performance or achievements to be materially different from the
results, performance or achievements that are or may be expressed
or implied by such forward-looking statements contained in this
news release and the company has made assumptions and estimates
based on or related to many of these factors. Such factors include,
without limitation: fluctuations in spot and forward markets for
silver, zinc, base metals and certain other commodities (such as
natural gas, fuel oil and electricity); fluctuations in currency
markets (such as the Peruvian sol versus the U.S. dollar); risks
related to the technological and operational nature of the
Company's business; changes in national and local government,
legislation, taxation, controls or regulations and political or
economic developments in Canada, the United States, Peru or other
countries where the Company may carry on business in the future;
risks and hazards associated with the business of mineral
exploration, development and mining (including environmental
hazards, industrial accidents, unusual or unexpected geological or
structural formations, pressures, cave-ins and flooding); risks
relating to the credit worthiness or financial condition of
suppliers, refiners and other parties with whom the Company does
business; inadequate insurance, or inability to obtain insurance,
to cover these risks and hazards; employee relations; relationships
with and claims by local communities and indigenous populations;
availability and increasing costs associated with mining inputs and
labour; the speculative nature of mineral exploration and
development, including the risks of obtaining necessary licenses
and permits and the presence of laws and regulations that may
impose restrictions on mining,; diminishing quantities or grades of
mineral reserves as properties are mined; global financial
conditions; business opportunities that may be presented to, or
pursued by, the Company; the Company's ability to complete and
successfully integrate acquisitions and to mitigate other business
combination risks; challenges to, or difficulty in maintaining, the
Company's title to properties and continued ownership thereof; the
actual results of current exploration activities, conclusions of
economic evaluations, and changes in project parameters to deal
with unanticipated economic or other factors; increased competition
in the mining industry for properties, equipment, qualified
personnel, and their costs.
Investors are cautioned against attributing undue certainty or
reliance on forward-looking statements. Although the Company has
attempted to identify important factors that could cause actual
results to differ materially, there may be other factors that cause
results not to be as anticipated, estimated, described or intended.
The Company does not intend, and does not assume any obligation, to
update these forward-looking statements or information to reflect
changes in assumptions or changes in circumstances or any other
events affecting such statements or information, other than as
required by applicable law.
Trevali's production plans at Caribou-Halfmile-Stratmat and
Santander are based only on Indicated and Inferred Mineral
Resources and not Mineral Reserves and do not have demonstrated
economic viability. Inferred Mineral Resources are considered too
speculative geologically to have the economic considerations
applied to them that would enable them to be categorized as Mineral
Reserves, and there is therefore no certainty that the conclusions
of the production plans and Preliminary Economic Assessment (PEA)
will be realized. Additionally where Trevali discusses
exploration/expansion potential, any potential quantity and grade
is conceptual in nature and there has been insufficient exploration
to define a mineral resource and it is uncertain if further
exploration will result in the target being delineated as a mineral
resource.
We advise US investors that while the terms "measured
resources", "indicated resources" and "inferred resources" are
recognized and required by Canadian regulations, the US Securities
and Exchange Commission does not recognize these terms. US
investors are cautioned not to assume that any part or all of the
material in these categories will ever be converted into
reserves.
